Aircraft air supplies delivered via compressed bleed air combined with the use of highly heated synthetic turbine engine oils has been a subject of concern since the early 1950’s and remains an ongoing issue to the present day. Dr. Susan Michaelis will present the findings of her PhD thesis on this subject examining the health and flight safety implications from exposure to unfiltered contaminated air in aircraft. Areas of specific interest include: the short and longterm adverse effects documented supporting a discrete occupational health syndrome, the frequency of exposure, an examination of air monitoring studies undertaken and the suitability of these to suggest the air is healthful or safe and a review of industry knowledge and actions spanning almost 6 decades. Synthetic jet engine oils heated to high temperatures have been long known to become toxic. This happens as a design and operational feature of using bleed air. It has become an accepted and expected occurrence within the aviation industry. The evidence presented warrants that precautionary measures be introduced to address this real health and flight safety issue.
